There was a distinct difference running the nectar versus FF trio used on my autos. The FF nutes were very hard to keep the ph of the soil in acceptable range. When watering/feeding with nectar the ph of the soil was only dropping like .2 - .4. Very easy to manage. I do not flush my pots/plants unless there is a problem. Seven plants running nectar that are now two weeks into flower and they have not shown any signs where they need to be flushed.
The autos that were fed FF needed to be flushed twice in a 90day grow cycle as the plants were showing signs of lockout.
Not downing the FF trio - but when my current supply is gone that will be the end of those nutes for me.
Good luck with your grow and tag me in when you start. I’m not running a journal but I’ll keep posting here with updates-pics.
